Changing Adolescents' Food-Related Behavior Via Nutrition Education, Adrienne Adams White Aug 1988

Changing Adolescents' Food-Related Behavior Via Nutrition Education, Adrienne Adams White

Doctoral Dissertations

A nutrition education behavior change strategy for secondary health classes was developed, implemented, and evaluated with 159 adolescents in 6 schools. The experimental design was pretest/posttest, treatment/control group with two treatment groups--one receiving only the behavior change strategy (BC) and one receiving the strategy plus a traditional knowledge-oriented component (BC+). Fundamental concepts of the behavior change strategy included personalization, goal setting, self-management, self-implementation, structured feedback, and structured self-evaluation. Based on a personal nutrient analysis, each adolescent in a treatment group selected improvement of one nutrient as a goal. Effectiveness of the strategy was tested by changes made in nutrient intake …


The Importance Of Competition For Food Resources In The Interaction Between Brook Trout (Salvelinus Fontinalis) And Rainbow Trout (Salmo Gairdneri), William E. Ensign Aug 1988

The Importance Of Competition For Food Resources In The Interaction Between Brook Trout (Salvelinus Fontinalis) And Rainbow Trout (Salmo Gairdneri), William E. Ensign

Masters Theses

The last 80 years have seen a drastic reduction in the range of the brook trout (Salvelinus fontinalis) the only salmonid native to the Southern Appalachians. Much of this range reduction is directly correlated with increases in the range of the introduced rainbow trout (Salmo gairdneri). The purpose of this study was to determine if competition for food resources plays a significant role in this interaction.

Stomach contents were obtained from sympatric and allopatric populations of brook and rainbow trout during June, July, August and September of 1987. Terrestrials comprised the majority of food items in …
